摘    要:为了避免秋季施肥时多次翻耕土壤而损失水分,提高肥水利用率和生产率,对渭北旱塬结合夏闲地翻耕施肥效应(在7月中旬和8月中旬)进行了研究。结果表明,该施肥方式能提高小麦产量、增加土壤NO3^--N的积累和提高肥水利用率及生产效率,同时也能缓解秋播劳力紧张的矛盾,有利于适时适墒播种。

关 键 词:渭北旱塬  小麦  施肥

Abstract:In dry plain of Weibei,combining ploughing summer fallow land and fertilization to increase the fertilizer and water efficiency,the super-advanced fertilization was studied. The results showed that the super-advanced fertilization could increase the wheat yield,the NO3--N accumulation in soil and the efficiency of fertilizer and soil water,especially the productivity of canter. Meanwhile it could relax the tight labour during the autumn sowing time.
Keywords:Weibei dry plain  Winter wheat  Fertilization
